使用ACF，我为一组特定的自定义帖子标签添加了一个自定义图像字段。我遇到的问题是我无法显示图像。是的，我已经添加了一个图像的标签和更新。
$term_id = 26;
$taxonomy_name = 'tags';
$termchildren = get_term_children( $term_id, $taxonomy_name );
foreach ( $termchildren as $child ) {
$term = get_term_by( 'id', $child, $taxonomy_name );
$tag_image = get_field('tag_image');
echo '<a href="?categories=' . $term->slug . '">'. $term->name . '</a>';
echo $tag_image; //this bit doesn't work :(
}
修正，新代码为:
<?php
$term_id = 26;
$taxonomy_name = 'tags';
$termchildren = get_term_children( $term_id, $taxonomy_name );
foreach ( $termchildren as $child ) {
$term = get_term_by( 'id', $child, $taxonomy_name );
$tag_image = get_field('tag_image', $term);
echo '<a href="?categories=' . $term->slug . '" class="one-third column">'. $term->name;
?>
<? if( !empty($tag_image) ): ?>
<img src="<? echo the_field('tag_image', $term); ?>" />
<?php endif;
echo '</a>';
}
?>

<?php
$term_id = 26;
$taxonomy_name = 'tags';
$termchildren = get_term_children( $term_id, $taxonomy_name );
foreach ( $termchildren as $child ) {
$term = get_term_by( 'id', $child, $taxonomy_name );
$tag_image = get_field('tag_image', $term);

<? if( !empty($tag_image) ): ?>
<img src="<? echo the_field('tag_image', $term); ?>" />
<?php endif;
echo '</a>';
